SPINNING MECHA'NISM.

I SPECIFICATION forming part of Letters Patent No. 510,909, dated December 19, 1893.

Application filed February 13, 1893. Serial No. 462,041. (No model.)

To all whom t may concern: as .fr to be drawn and which faces are prefer- Be it known that I, DAVD P. GERMAN, of ablycovered withleatheror someother similar New Hartford, in the county of Oneida and material. State of New York, have invented certain new Mounted on top of the rollers c, b and c are 5 5 5 and useful Improvements in Spinning Mechrollers f, g and h. v These rollers are mounted anism; and I do hereby declare that the folin adjustable bearings or between guiding lowing is a full, clear, and exact description walls which engage on the journals l and 2 of of the invention, which will enable others each roller and hold the rollers in place on top skilled in the art to which it appertains to of each of the lower rollers. The rollers f, g 6o to make and use the same, reference being had and h are each provided with faces z' and j to the accompanying drawings, and to the letcoinciding with the faces d and e of the lower ters and gures of reference marked thereon, rollers and adapted to engage the threads to be which form part of this specification. drawn in the operation of spinning or other- My invention relates to an improvement in wise. 6 5

In the presentconstruction, the fulcrum piece may be adj usted minutely by removing the end of the lever and giving the fulcrum piece a quarter turn, or more by quarters as is required. Further than this, there are four times the amount'of Wear as there are four shoulders as shown ats on which the lever engages and which have to be worn out before the fulcrum piece is useless. gaging in the opening 8 in the fulcrum piece also prevents lateral movement of the lever and holds the lever always in the same position with the same length of arm t tween the fulcrum point and the Weighted point.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a lever having a nose or projection, and a fnlcrum piece having transverse stop or openings at angles to each other to receive the end of the lever, and a recessor opening above the transverse slotsfor receiving the nose or projection, substantially asset forth.

2. The combination of a lever having an up- The nose 7 of the arm en-V wardly turned nose or projection on its fulcrum end and a fnlcrum piece having a screw threaded stem, and ahead having transverse slots for receiving the end of the lever, and a recess or depression at the intersection of the slots to receive the nose or projection on the lever, substantially as set forth.

3. The combination with a suitable support, of a fulcrum piece having means of adjustment bodily with reference to the support, and having an opening in the axial line thereof, and radial slots or openings from the axial opening to the exterior, the end portion of the body at the upper end of each radial opening serving as a fulcrum, and a lever having a fulcrum end adapted to be placed in either of the radial openings, with a projection adapted to engage in the axial opening, substantially as set forth. p

In Witness whereof I have aixed mysignature in' presence of two Witnesses.
